Maryland Estates and Trusts Section 8-110

      (a)      Upon proof of an unsecured claim which will become due at some future time, and which has not been compromised pursuant to § 7-401 or authority conferred by the will, the court shall direct the investment of an amount which will provide for the payment of the claim when it becomes due.

      (b)      When a creditor holds a security for an allowable claim due at some future time he may rely on his rights under § 8-111 or may file his claim as an unsecured claim not yet due, with the right of withdrawing the claim prior to the taking of action upon it, and rely on his rights as provided in § 8-111 after the withdrawal.
